Description

packaging structure

technical field

The present invention relates to a packaging structure; in particular, the present invention relates to an easily disassembled packaging structure for loading display panels or other fragile items.

Background technique

The packaging of fragile items has always been an important issue during product delivery. Inadequate packaging often results in damage to items during delivery, which in turn increases production costs. In particular, fragile items with special sizes and shapes, such as liquid crystal glass or display panels, are prone to stress concentration due to their special sizes and shapes, and increase the possibility of damage.

Taking the transportation of display panels as an example, traditionally, when transporting display panels, it is usually necessary to add cushioning materials such as Styrofoam to the cartons to reduce the direct impact of external forces on the display panels. As shown in FIG. 1 , a traditional packaging structure includes an outer carton 10 , a middle carton 20 and a cushioning material 30 . The buffer material 30 is disposed in the middle carton 30 , and the outer carton 10 is covered outside the middle carton 20 and the buffer material 30 . After packing, the display panel 11 can be protected by the buffer material 30 . However, in order to save the use of the cushioning material 30, generally the cushioning material 30 is only used locally, rather than comprehensively covered. Under the condition of insufficient filling, the fixing between the buffer material 30 and the middle carton 20 is more important. In order to effectively fix the cushioning material 30 on the middle carton 20, glue is generally used as an adhesive for fixing. However, the adhered cushioning material 30 and the middle carton 20 are not easy to disassemble, and require a large storage space for waste materials after use. In addition, since it is not easy to disassemble, the waste formed after use cannot be recycled, causing environmental problems.

Contents of the invention

The main purpose of the present invention is to provide a packaging structure with a more convenient assembly and disassembly process.

Another object of the present invention is to provide a packaging structure that has a reliable positioning effect of the cushioning material.

Another object of the present invention is to provide a packaging structure that can save space for waste storage.

The packaging structure of the present invention includes a casing and a buffer material. The casing mainly includes a bottom plate and a side wall, wherein the side wall intersects with the bottom plate and forms an angle. The cushioning material is arranged on the bottom plate of the casing, and its two ends are in contact with the two side walls of the casing respectively. A slot and a jaw are formed on the end of the buffer material. The slot extends from the end toward the inside of the cushioning material and is inclined toward the bottom plate. The jaw is located on a side of the slot facing the side wall of the casing, and extends away from the bottom plate. The top end of the jaw part and the end part of the cushioning material jointly enclose the opening on the end part of the card slot, and form the upper and lower sides of the opening.

A first tongue is formed on the side wall of the housing. The root of the first tongue piece is connected to the side wall and is bent toward the inside of the casing; while the free end of the first tongue piece extends obliquely toward the bottom plate of the casing. The first tongue protrudes into the slot from the opening of the slot, wherein the back side and top end of the jaw interfere with the first tongue and restrict the first tongue from entering and leaving the slot. When the buffer material is moved away from the bottom plate by an external force, the first tongue supports the inner surface of the bottom in the slot, and transmits the resulting reaction force to the side wall, and limits the movement of the buffer material away from the bottom plate. displacement. In addition, the first side and the second side of the first tongue are in contact with the first side stop portion and the second side stop portion of the cushioning material, so as to limit the displacement of the cushioning material in the conflicting direction.

Through the above-mentioned design, the engagement relationship between the first tongue piece and the slot can simultaneously limit the displacement of the buffer material toward both sides and away from the bottom plate. In addition, since the bottom plate is provided under the buffer material, the buffer material cannot move downward. Since the main movable directions are all provided with displacement restrictions, when the first tongue piece engages with the locking groove, the buffer material can be positioned in the housing and cannot be displaced arbitrarily. In addition, when assembling, it is only necessary to press the first tongue piece inward into the slot, and when disassembling, it is only necessary to push the first tongue piece outwards out of the jaw, and the directionality of assembly and disassembly is greatly improved .

The packaging structure may further include an outermost box. Two opposite ends of the box are respectively provided with a first shell and a second shell. The first shell and the second shell are respectively combined with the cushioning material in the connection manner of the tongue piece and the slot. When the display panel or other items to be boxed or transported are put into the box, the buffer materials located at opposite ends of the box can provide protection for the display panel or other items in different directions and reduce the impact caused by external forces.

Detailed ways

The present invention provides a packaging structure, preferably a box structure applied to packaging. However, in different embodiments, the packaging structure of the present invention can also be used as a separate cushioning packaging material. In a preferred embodiment, the packaging structure of the present invention is used for packaging vulnerable sheet items, such as liquid crystal glass, display panels, or general glass. However, in different embodiments, the packaging structure of the present invention can also be used for packaging vulnerable items of other shapes.

In the embodiment shown in FIG. 2 , the packaging structure includes a casing 200 and a cushioning material 300 . The casing 200 mainly includes a bottom plate 210 and a side wall 230 , wherein the side wall 230 intersects with the bottom plate 210 and forms an angle. In this embodiment, the side wall 230 is bent from one end of the bottom plate 210 and extends upwards, and is perpendicular to the bottom plate 210 . In addition, the casing 200 is preferably made of cardboard; however, in different embodiments, the casing 200 can also be made of plastic or other materials.

As shown in FIG. 2 , the buffer material 300 is disposed on the bottom plate 210 of the casing 200 . The cushioning material 300 is preferably formed as a strip, and two ends of the buffering material 300 respectively abut against the two sidewalls 230 of the casing 200 . In this embodiment, since the base plate 210 is a rectangle, the cushioning material 300 straddles the rectangle formed by the base plate 210 . The top of the cushioning material 300 is preferably formed with a plurality of grooves 301 , and the grooves 301 can provide a positioning function when the display panel or other items to be packed or shipped are loaded. Two sides of the buffer material 300 are respectively formed as a first side stop portion 321 and a second side stop portion 322 . The first side blocking portion 321 and the second side blocking portion 322 are preferably two opposite side surfaces of the buffer material 300 , but may also be other structures disposed on the side of the buffer material 300 . In a preferred embodiment, the cushioning material 300 is made of expanded polypropylene (EPP), but it can also be made of other organic resin or rubber materials.

In the embodiment shown in FIG. 2 , an engaging groove 330 and a jaw 350 are formed on the end portion 310 of the cushioning material 300 . As shown in Figures 2 and 3, the slot 330 extends from the end 310 toward the inside of the cushioning material 300, and is inclined toward the bottom plate 210; the inclination angle can be between 0° and 90°, but is relatively The best place is between 30 degrees and 45 degrees. In this embodiment, the section of the slot 330 extends straight; however, in different embodiments, the slot 330 may also extend upward or curved, or bend at different angles. The jaw 350 is located on the side of the slot 330 facing the side wall 230 of the housing 200 and extends away from the bottom plate 210; The bottom of the back side is connected to the body of the cushioning material 300 . Since the back side of the jaw 350 is formed with a slot 330, and only the bottom of the back is connected to the body of the cushioning material 300, the jaw 350 is allowed to deform or deform relative to the slot 330 when pressed inward or pushed out by an external force. displacement. In addition, in addition to the structural design, the jaw portion 350 itself preferably also has elasticity, so that after displacement or deformation, it can return to its original position after the external force is released.

As shown in FIGS. 2 and 3 , the top end 353 of the jaw portion 350 and the end portion 310 of the cushioning material 300 together define the opening 331 of the slot 330 at the end portion 310 , and form the upper and lower sides of the opening 331 . In this embodiment, the opening 331 of the locking groove 330 at the end portion 310 crosses the entire surface of the end portion 310 and extends to the first side blocking portion 321 and the second side blocking portion 322 to form a side opening 333 . However, in different embodiments, the opening 331 may also be formed only on the surface of the end portion 310, so that the periphery of the opening 311 is formed in a closed state.

As shown in FIG. 2 , a first tongue 510 is formed on the side wall 230 of the housing 200 . The base of the first tongue piece 510 is connected to the side wall 230 and is bent toward the housing 200 ; while the free end 511 of the first tongue piece 510 extends obliquely toward the bottom plate 210 of the housing 200 . In a preferred embodiment, the shape of the first tongue piece 510 can be cut directly on the side wall 230 and the root part is kept to connect to the side wall 230, and then the cut part is pushed into the housing 200 to form the first tongue piece 510. However, in different embodiments, the first tongue piece 510 can also be combined on the side wall 230 by sticking, locking or other methods.

As shown in FIG. 3 , the first tongue 510 extends into the slot 330 from the opening 331 of the slot 330 , wherein the back side and the top end 353 of the jaw 350 interfere with the first tongue 510 and restrict the first tongue 510 . In and out of the card slot 330 . In other words, the first tongue piece 510 needs to have sufficient length, preferably longer than the linear distance from the root of the first tongue piece 510 to the top end 353 of the jaw portion 350 . Therefore, when the first tongue piece 510 is pushed into the slot 330 from the outside, the first tongue piece 510 presses the jaw portion 350 to generate rotation, displacement or deformation, so as to enter the slot 330 through the jaw portion 350 . When the first tongue piece 510 enters the slot 330 , the jaw portion 350 returns to its original position to restrict the first tongue piece 510 from leaving the slot 330 .

As shown in FIG. 3 , the free end 511 of the first tongue 510 is in contact with the bottom inner surface 332 of the engaging groove 330 . When the cushioning material 300 is moved away from the bottom plate 210 by an external force, the first tongue piece 510 supports the bottom inner surface 332 in the slot, and transmits the resulting reaction force to the side wall 230, thereby limiting the cushioning The displacement of the material 300 away from the bottom plate 210. In addition, the first side 710 and the second side 720 of the first tongue 510 interfere with the first side stop 321 and the second side stop 322 of the cushioning material 300, so as to limit the movement of the cushion 300 in the conflicting direction. displacement. As shown in FIG. 2 and FIG. 4 , the first side 710 and the second side 720 of the first tongue 510 are respectively located on two sides of the free end 511 . In this embodiment, the first side 710 of the first tongue 510 is formed with a first protrusion 711 protruding from the free end 511 , and the second side 720 is formed with a second protrusion 721 protruding from the free end 511 . As shown in FIG. 4 , the width of the first tongue 510 is greater than the width of the opening 331 of the slot 330 . Since the lateral opening 333 of the card slot 330 on the first side stopper 321 and the second side stopper 322 is connected to the opening 331, the first side 710 and the second side 720 can respectively protrude from the sides of the two sides. Outside the opening 333 , the first protruding portion 711 and the second protruding portion 721 are in contact with the outer surfaces of the first side blocking portion 321 and the second side blocking portion 322 near the engaging groove 330 . As shown in FIG. 4 , the first protruding portion 711 and the second protruding portion 721 clamp the buffer material 300 from two sides respectively, and limit the displacement of the buffer material 300 toward both sides.

Through the above design, the engaging relationship between the first tongue piece 510 and the slot 330 can limit the displacement of the cushioning material 300 toward both sides and away from the bottom plate 210 at the same time. In addition, since the bottom plate 210 is disposed under the buffer material 300 , the buffer material 300 cannot move downward. In addition, since the side walls 230 are preferably arranged in pairs, and the buffer material 300 is interposed between two opposite side walls 230 , the buffer material 300 cannot move toward or away from the side walls 230 . Since the main movable directions are all provided with displacement restrictions, when the first tongue piece 510 engages with the slot 330 , the cushioning material 300 can be positioned in the housing 200 and cannot be displaced arbitrarily. In addition, it is only necessary to press the first tongue piece 510 inwardly into the slot 330 during assembly, and only need to push the first tongue piece 510 out of the jaw portion 350 during disassembly. The direction of assembly and disassembly Sexuality was greatly improved.

In another embodiment, as shown in FIGS. 5A and 5B , in addition to the first tongue 510 , a second tongue 520 may also be added. In this embodiment, the first tongue piece 510 and the second tongue piece 520 are arranged symmetrically; however, in different embodiments, the first tongue piece 510 and the second tongue piece 520 may also be asymmetrical in consideration of functionality. set up. For example, the two can be adjusted to adopt different lengths, different bending angles or different structural designs. In the embodiment shown in FIG. 5A, the second tongue piece 520 is arranged side by side with the first tongue piece 510, and the free ends 511, 521 of both extend toward the bottom plate 210; The tongue 520 is inverted so that its free end 521 extends in the opposite direction. As shown in FIG. 5A and FIG. 5B , the first tongue piece 510 and the second tongue piece 520 respectively form a first convex portion 711 and a second convex portion 721 on the outward side, and protrude from the free ends 511, 521 respectively. outside. After being inserted into the slot 330 , the first protrusion 711 and the second protrusion 721 can respectively clamp the buffer material 300 from both sides of the buffer material 300 .

As shown in FIG. 5A and FIG. 5B , a bridging portion 550 is interposed between the first tongue piece 510 and the second tongue piece 520 . Upper and lower ends of the bridging portion 550 are respectively connected to portions of the side wall 230 located above and below the first tongue 510 and the second tongue 520 . In a preferred embodiment, the shape of the first convex portion 711 and the second convex portion 721 is cut out on the side wall 230 first, and the root portion is left to connect to the side wall 230, and then the cut part is pushed into the casing 200 to A first tongue piece 510 and a second tongue piece 520 are formed. When cutting the shape of the first tongue 510 and the second tongue 520, the part of the bridging portion 550 can be reserved between the two without cutting; when the first tongue 510 and the second tongue 520 are pushed inward, , the bridging portion 550 can be directly formed. Through the setting of the bridging portion 550, the protruding portion 570 left after cutting the first tongue piece 510 and the second tongue piece 520 on the side wall 230 can be connected to the upper side wall 230 part, so as to prevent the protruding portion 570 from Warped or bent outward.

In the embodiment shown in FIG. 6A and FIG. 6B , when the buffer material 300 is disposed at the bottom part of the housing 200 , the structure of the first tongue piece 510 can be selectively adjusted. As shown in FIG. 6A , in addition to the bottom plate 210 and the side wall 230 , the casing 200 further includes a back wall 250 perpendicular to the bottom plate 210 and the side wall 230 respectively. The back wall 250 is in contact with the side wall 230 and stands together on the bottom plate 210 . As shown in FIGS. 6A and 6B , when the second side stop portion 322 of the cushioning material 300 fits or touches the back wall 250 , only the first side edge 710 of the first tongue 510 can protrude outward to form a second side. A protrusion 711 , but the second side 720 does not protrude outward, so there is no second protrusion 721 . In this embodiment, since one side of the buffer material 300 leans against the back wall 250 of the housing 200 , the buffer material 300 cannot move toward this side without the second protrusion 721 .

In addition, in the embodiment shown in FIGS. 7A and 7B , when the second side stop portion 322 of the cushioning material 300 abuts against the back wall 250 , a third tongue piece 530 may also be formed on the back wall 250 . Similar to the first tongue piece 510 , the third tongue piece 530 is also bent toward the inside of the casing 200 and has a free end 531 extending obliquely toward the bottom plate 210 . The backside locking groove 360 is formed on the second side blocking portion 322 and the backside jaw portion 365 is located on a side of the backside locking groove 360 facing the back wall 250 . The back side jaw portion 365 extends away from the bottom plate 210 , and its top end and the second side blocking portion 322 together define the back side opening 361 of the back side locking groove 360 . The relationship between the third tongue piece 530 and the backside engaging groove 360 and the backside jaw portion 365 is similar to the relationship between the aforementioned first tongue piece 510 and the engaging groove 330 . As shown in Figures 7A and 7B, the third tongue 530 can extend from the back opening 361 into the back slot 360; the back jaw 365 interferes with the third tongue 530 and restricts the third tongue 530 from entering and exiting. 360 card slots on the back side. When the external force tries to make the cushioning material 300 move out of the housing 200 , the free end 531 of the third tongue 530 collides with the inner surface of the backside engaging groove 360 and limits the displacement of the cushioning material 300 away from the bottom plate 210 .

8A and 8B, the length of the opening 331 of the slot 330 in the direction transverse to the end 310 of the cushioning material 300 is smaller than the thickness of the end 310, so the position of the opening 331 is only limited to the end 310 and not Expand to the first side stop portion 321 and the second side stop portion 322 . At this time, the opening 331 has a closed edge on the end portion 310 , and the inner surfaces of the first side blocking portion 321 and the second side blocking portion 322 are respectively formed as two inner wall surfaces of the locking groove 330 . In this embodiment, the width of the first tongue portion 510 is smaller than the thickness of the buffer material 300 , and can just extend into the opening 331 . Inner surfaces of the first side blocking portion 321 and the second side blocking portion 322 are respectively in contact with the first side 710 and the second side 720 of the first tongue 510 to clamp the first tongue 510 . Such an arrangement can prevent the first side blocking portion 321 or the second side blocking portion 322 from moving toward the first tongue portion 510 , thereby positioning the relative positional relationship between the buffer material 300 and the side wall 230 .

As shown in FIG. 8C , the buffer material 300 includes a first support plate 303 , a second support plate 305 and a shock-absorbing layer 307 . The shock-absorbing layer 307 is interposed between the first support plate 303 and the second support plate 305 to form a sandwich plate structure. Compared with the first supporting board 303 and the second supporting board 305 , the shock-absorbing layer 307 has less rigidity to provide better shock-absorbing and cushioning capabilities. In a preferred embodiment, the shock-absorbing layer 307 is made of 15 times expanded polypropylene (EPP). However, in different embodiments, the shock-absorbing layer 307 can also be made of foamed polypropylene material with other multiples such as 30 times or 45 times, or made of other organic resin or rubber materials. The first supporting board 303 and the second supporting board 305 are made of 30 times expanded polypropylene (EPP). However, in different embodiments, the second cushioning material 200 can also be made of foamed polypropylene material with other multiples such as 15 times or 45 times, or made of other organic resin or rubber materials. As shown in FIG. 8C , the first support plate 303 and the second support plate 305 are respectively formed as a first side stop portion 321 and a second side stop portion 322 . Two sides of the first tongue piece 510 respectively interfere with inner surfaces of the first support plate 303 and the second support plate 305 .

As shown in FIG. 9A , the opening 331 of the locking slot 330 has an opening width d in a section. In a preferred embodiment, the opening width d is not less than the thickness of the first tongue portion 510 , and is preferably equal to the thickness of the first tongue portion 510 . In addition, the section widths of the slots 330 at different depths can be kept the same, that is, the slots 330 are formed with equal diameters. However, in different embodiments, as shown in FIG. 9B , the cross-sectional width of the locking groove 330 can also be gradually increased from the opening 331 to the bottom, so that the cross-sectional width D at the bottom is greater than the cross-sectional width d of the opening. In addition, the outer surface 355 of the jaw portion 350 can also be inclined from the bottom to the slot 330 by a leading angle θ, so as to increase the convenience of the first tongue piece 510 when entering and exiting.

In addition, in the embodiment shown in FIG. 9C , the slot 330 can be divided into an opening section 338 and a turning section 339 . The opening section 338 is a portion extending directly from the opening 331 , and the turning section 330 is a portion near the bottom of the slot 330 . The turning section 330 communicates with the opening section 338 and is bent at an angle from the opening section 338 . In a preferred embodiment, the first tongue piece 510 protrudes into the opening section 338, and interferes with the inner surface at the junction of the opening section 338 and the turning section 339; however, in a different embodiment, the first tongue piece 510 It can also protrude into the transition section 339 . As shown in FIG. 9C , the turning section 339 is located on the back side of the jaw 350 , and when the jaw 350 is pressed inward, the turning section 339 can provide a space for the jaw 350 to retract inwardly.

As shown in FIG. 10 , the packaging structure may further include an outermost box 100 . A first housing 201 and a second housing 202 are respectively provided at two opposite ends of the box body 100 . The first shell 201 and the second shell 202 are respectively combined with the cushioning material 300 through the above-mentioned connection manner of the tongue and the slot. When the display panel 110 or other items to be boxed or transported are put into the box body 100, the buffer materials 300 located at opposite ends of the box body 110 can provide protection for the display panel 110 or other items in different directions and reduce external force. the impact. In addition, the groove 301 on the buffer material 300 can provide proper positioning of the display panel 110 or other items.

In the embodiment shown in FIG. 11 , the housing 200 is not provided with a bottom plate 210 , but is only surrounded by a side wall 230 and a back wall 250 . The difference from the previous embodiments is that an upper tongue 810 and a lower tongue 820 are formed on the side wall 230 . The structure of the upper tongue 810 and the lower tongue 820 is similar to that of the aforementioned first tongue 510, except that the upper tongue 810 and the lower tongue 820 are collinearly arranged, that is, the direction in which the two extend from the connection position with the side wall 230 are collinear; the collinear relationship here mainly refers to the state before the upper and lower tongues 810 and 820 are bent into the housing 200 . The first free end 811 of the upper tongue 810 and the second free end 821 of the lower tongue 820 extend in different directions, and both are inclined toward the inside of the housing 200 . To correspond to the upper tongue 810 and the lower tongue 820 , the end 310 of the cushioning material 300 is also formed with an upper locking groove 830 and a lower locking groove 840 corresponding to the upper tongue 810 and the lower tongue 820 respectively. An upper jaw portion 835 and a lower jaw portion 845 are formed on the end portion 310 and are respectively located on a side of the upper locking groove 830 and the lower locking groove 840 facing the side wall 230 . Since the upper tongue 810 and the lower tongue 820 extend in different directions, the upper jaw and the upper jaw also cooperate to extend in the opposite direction, and together with the end 310 of the cushioning material 300 respectively enclose the upper groove 830 and the lower groove 840. Open your mouth.
